The Les Misérables star announced Tuesday at the Givenchy press launch for their new Live Irrésistible fragrance, which she is the spokesmodel for, that she and Sadoski — best known for his role in the television series Life in Pieces — are expecting a baby together.

At the event, Seyfried, 30, wore a body-hugging black mini dress by Givenchy that made no secret of her exciting news.
